Explore our signature range of industrial and heavy-duty oils, designed to withstand extreme thermal pressures and reduce operating friction.
Industrial heavy equipment operates under multi-axis dynamic stresses, requiring gear lubrication solutions that go far beyond standard wear reduction. Gear teeth engage under extreme boundary lubrication conditions. Without a precise additive chemical balance, metal-to-metal contact can trigger micropitting, high-temperature degradation, and eventual mechanical seizure.
Modern industrial environments demand gear oils with robust chemical resilience. High-torque gearboxes require L-CKD heavy-duty gear oils formulated with sulfur-phosphorus extreme pressure (EP) chemistry. These active chemical complexes form solid microscopic boundary films on gear flanks. This protects metal structures during peak shock loads and maintains film strength across wide temperature ranges.
At Shandong Longhai Lubrication Technology Development Co., Ltd., we combine over 15 years of technical expertise with advanced blending platforms. We develop formulations that match and exceed strict international specifications, ensuring system longevity for operators worldwide.
Precision-engineered systems processing high-performance base stocks and performance-critical additive chemistries.
Shandong Longhai Lubrication Technology Development Co., Ltd., established in 2009 and based in Zibo, Shandong, operates a world-class manufacturing facility covering 131 acres. Our plant has a capacity of 200,000 tons annually. This setup allows us to reliably meet large-scale OEM orders and global procurement requirements.
Our advanced production lines feature automated, closed-loop batch blending. We utilize high-precision metering systems to guarantee a filling accuracy tolerance of 1‰ to 2‰. This system increases packaging throughput speed by 20% to 35% compared to conventional methods. By minimizing human error, we maintain consistent viscosity indices and additive levels across every batch we produce.
We use pure API Group II and Group III hydrocracked mineral base oils, as well as synthetic Polyalphaolefins (PAO) and esters. Combined with additive chemistry developed under our international partnership with the British "A Ba" series, we produce premium-grade gear, hydraulic, and engine oils.
Our products are engineered for maximum reliability, backed by rigorous quality certifications and product liability insurance.
Our production facility is fully certified to international standards, including ISO 9001:2015 for quality management, ISO 14001 for environmental systems, and ISO 18001 for occupational health safety.
Our automatic transmission fluids carry formal Mercedes-Benz approvals, verifying their shear stability, friction profile, and performance under extreme conditions.
For added reliability, our entire product portfolio is insured by the People's Insurance Company of China (PICC), offering comprehensive quality protection to our global distribution partners.
Helping global operations navigate shifting industrial demands with advanced fluid technology.
High-speed electric vehicle (EV) drivetrains require specialized fluid designs. Modern formulations must offer high dielectric strength, thermal cooling capacity, and copper protection, alongside traditional gear wear prevention.
To minimize equipment downtime and reduce waste oil footprints, heavy industrial operations require gear fluids that offer superior oxidation stability and longer service life.
Global environmental standards are driving a shift toward ashless, zinc-free, and biodegradable lubricant formulas, helping industrial operations reduce their ecological impact.
Engineered formulations designed to perform reliably across diverse industrial environments.
Heavy-duty excavators, crushers, and grinders operate under heavy shock loads and abrasive dust. Our L-CKD gear oils protect gears from severe wear and micropitting under these challenging conditions.
Wind turbine gearboxes operate in hard-to-reach locations with wide temperature shifts. Our synthetic gear lubricants maintain stable viscosity and resist oxidation, helping to extend drain intervals.
Propulsion thrusters and deck winches are constantly exposed to moisture. Our lubricants offer strong demulsibility and corrosion protection to prevent oil emulsification.
Continuous casting machines operate in high-temperature environments. Our high-viscosity index formulations maintain a strong protective fluid film, preventing oil breakdown.
Innovation drives our manufacturing approach. We invest more than 5% of our annual revenue directly back into our dedicated R&D division and state-of-the-art testing laboratories.
Our laboratories are equipped to perform detailed diagnostics on incoming base stocks and finished blends, analyzing parameters like kinematic viscosity, flash points, pour points, and four-ball wear scar diameters. This continuous testing ensures that every lubricant batch matches its technical specifications before leaving the factory.
Through research partnerships with technical universities and testing laboratories, we continue to develop specialized formulations, including high-efficiency worm gear oils and synthetic compressor lubricants.
